精煤脫水篩處理量的計算

發布者：隆中重工發布日期：2014-04-03

在选购脫水篩时，筛分物料特性和产量需求是选择的重要依据，其中产量需求就是脫水篩的处理量，常规单位是吨/時。隆中重工以脫水篩筛分煤为例，对*煤脫水篩处理量进行分析，

在选购脫水篩时，筛分物料特性和产量需求是选择的重要依据，其中产量需求就是脫水篩的处理量，常规单位是吨/時。

隆中重工以脫水篩筛分煤为例，对*煤脫水篩处理量进行分析，供用户参考：

脫水篩处理量Q：Q＝q· F· t/h

式中 F指篩面面積(m2),F=B(m)×L(m)；

Q指單位篩面面積的處理能力，t/m2· h，其數可參考表1。

表1：篩分設備單位面積處理能力

名稱	篩分種類	不同篩孔尺寸(mm)的單位面積處理能力(t/m2.h)
名稱	篩分種類	100	75	50	25	13(10)	6	0.5	0.25
單軸慣性脫水篩	預先篩分	100～120	80～90	60～70
雙軸慣性脫水篩	准備篩分幹法准備篩分濕法煤脫水分J 末煤脫水末煤脫泥粗煤泥脫水塊煤脫介塊中煤脫介塊矸石脫介末*煤脫介末中煤脫介末矸石脫介			35～40	20～25	8～10 12～14 14～16 11～12 10～11 9～10	4～5 8～10 10～12 9～10 8～9 7～8	5～7 7～8 2～2.5 2～3 1.5～2 1.5～2	1～1.5

1、在重介質選煤去除矸石的過程中，同時伴隨著脫水和脫介；脫介篩分，脫泥篩分屬于濕法篩分。

2、等厚篩的處理量爲圓振篩處理量的1.6倍。

3、G頻篩的處理能力一般爲q = 2-3t/m2.h。

*煤脫水篩处理量的计算方法如上所述。选择*煤脫水篩的型号时，处理量并不是*一的选型依据，还有考虑筛分物料特性、物料含水量、成品要求以及生产环境等，都在考虑范围之内。建议您電話咨詢隆中重工技术人员，可为您专业解答脫水篩的相关疑问。

"I can't do it," he gasped, "I can't really. You must—excuse me." "Why, what's this?" he exclaimed. "What does the game mean?" (1.) Can the driving power be employed directly to shift the belts of a planing machine?—(2.) Why are planing machines generally constructed with a running carriage instead of running tools?—(3.) What objection exists in employing a train of spur wheels to drive a planing machine carriage?—(4.) What is gained by shifting the belts of a planing machine differentially?—(5.) What produces the screeching of belts so common with planing machines?—(6.) What conditions favour the shifting of planing machine belts? “Stuck. It won’t come back. It’s the jinx! Hoodoo! We’re heading down for the bay and I can’t get the nose up!” "Yes," he said, emptying the soap-caked water from the Indian basket wash basin upon the earth floor;[Pg 27] "why?"—"I used to know him in '61. He came up to the Mescalero Agency then, not long before the Texans overran the place. I recollect there was a sort of blizzard and it was seventeen below. He came after a kid me and another feller'd been looking after. Pretty little cuss, about four years old. I gave her her first bow'n arrow." "Say!" she apostrophized. "Cor—po—ral Ell—iott. Cor—po—ral Ell—iott!" "But that's the point—don't you see?" As luck would have it, the only piece that was not his was the Moor's most characteristic feature, the knob of firs that made it a landmark for miles round. While they still stood men could still talk of and point at Boarzell, but when he had cut them down, grubbed up the gorse at their roots, ploughed over their place—then Boarzell would be lost, swallowed up in Odiam; it would be at most only a name, perhaps not even that. Sometimes Reuben shook his fist at the fir clump and muttered, "I'll have you yet, you see if I d?an't, surelye." HoME WWW822WWWSSCOM ENTER NUMBET 0010www.aac12.com.cn
